   The <span class="command"><strong>db_tuner</strong></span> utility analyzes the data in a btree database, and suggests a page size that is likely to deliver optimal operation.
 </p>
      <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
        <h3 class="title">Note</h3>
        <p>
 The <span class="command"><strong>db_tuner</strong></span> utility assumes that databases are compacted when analysing the data. The analysis is based on a static view of the data and the data access and update patterns are not take into account. 
 </p>
      </div>
      <p>
   The options are as follows:
 </p>
      <div class="itemizedlist">
        <ul type="disc">
          <li>
            <p>
       <span class="bold"><strong>-c</strong></span>
     </p>
            <p>
    Specify a value of the cachesize, otherwise, the default value will
        be set.
     </p>
          </li>
          <li>
            <p>
       <span class="bold"><strong>-d</strong></span> 
     </p>
            <p>
    Display database statistics for the specified file. If the database contains multiple databases and the -s flag is not specified, the statistics are for the internal database that describes the other databases the file contains, and not for the file as a whole. 
     </p>
          </li>
          <li>
            <p>
       <span class="bold"><strong>-h</strong></span> 
     </p>

            <p>
       <span class="bold"><strong>-s</strong></span>
